摘要：

Nonspecular effects for reflection from a lossy dielectric are studied under the paraxial approximation. It is shown that lateral shifts larger than 100 wavelengths are obtained for an angle of incidence close to the Brewster angle. Furthermore, it is shown that a three-dimensional Gaussian beam with a circular cross section becomes on reflection near the Brewster angle a Gaussian beam with an elliptical cross section. In addition, an evaluation of the accuracy of the paraxial approximation is done by comparison with an exact calculation.
